I S AES ALBERT S. WALIDREP, OF CHICAGO, ILLINOIS.

GAR-COUPLING.

Specification of Letters Patent.

Patented Apr.9, 1912.

Application filed August 18, 1910. Serial No. 577,787.

To all whom it may concern Be it known that I, ALBERT S. VVALonuP, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Car-Couplers, of which the following is a specification.

My present invention relates to car couplers, and more particularly to asafety attachment therefor in the form of improved knuckles adapted toprevent the couplers from dropping and disengaging, should the draw barsbecome broken or otherwise disengaged from their supports.

My object is to provide the knuckles with parts which will be operativeat all times and yet yield, should the draw heads come together when theknuckles are closed.

Vith the foregoing in mind, my invention resides in the features ofconstruction and arrangement shown in the accompanying drawing, inwhich,

Figure 1, is a side elevation of coupled draw heads provided with myimprovements. Fig. 2, is a similar view of the same abutting one anotherwhen the couplers are brought together with the knuckles closed. Fig. 3,is an elevation of one of the knuckles, and, Fig. 4, is a verticalsection taken on line 4-4 of Fig. 3.

Referring to these figures, the draw heads 1, at the ends of the drawbars 2, have, as usual, the knuckles 3, pivoted thereto, and having atail l which is engageable by the locking device (not shown) in theordinary manner.

In accordance with my invention, the lower ends of the knuckles 3 areextended below the draw heads 1, and provided with projections 3 upontheir lower ends to extend within the recesses at the upper ends of theextension parts 5, and apertured to receive a pivot pin 5, projectingalso through portions of the said parts 5, to form a hinge and pivot theparts 5, for swinging movement. The end of the projection 3 of each ofthe knuckles is beveled to conform with the beveled base of the recessof its pivoted part 5, so as to prevent the latter from swinging exceptin a direction toward the draw head, and said part 5, is normally heldin vertical alinement with the knuckle by means of its weighted arm 7,forming an extension of its lower flange 6. In this manner, when the twodraw heads come together as shown in Fig. 1, and properly lock, thepivoted part 5 of each, is in position so that its flange will receivethe draw head of the opposite coupler, should its draw bar become brokenor otherwise detached from its supports (not shown). In like manner,should two draw heads come together with their knuckles closed, theflanges 6, striking one another, will cause the extension parts 5, toswing away from one another as shown in Fig. 2 and thus prevent fractureof these parts.

Having thus described my invention, I claim,

1. In a car coupler, the combination with a draw head and knuckle, of anextension part pivoted to the lower end of the knuckle to swing in adirection toward the draw head, a coupler support carried by saidextension part.

2. In a car coupler, the combination with a draw head and knuckle, of anextension part pivoted to the lower end of the knuckle to swing in adirection toward the draw head, and means to limit the movement of saidextension part in the opposite direction, said extension part having alower coupler supporting flange.

3. In a car coupler, the combination with a draw head and knuckle, of anextension part for the knuckle, said knuckle having a lower aperturedprojection provided with a beveled end, and said extension part havingan upper recess to receive said projection, and provided with a beveledbase to conform to said projection and limit movement of the extensionpart in one direction. and a pin extending through portions of saidextension part and through said knuckle projection to form a hinge, saidextension part having a lower coupler supporting flange provided with aweighted arm.

In testimony whereof I afflx my signature in presence of two witnesses.
